MUNICH — Bridie O'Halloran drank the first beer of her life at Oktoberfest.

Oktoberfest has opened in Munich after the ceremonial beer keg-tapping. Mayor Dieter Reiter officially started the 189th Oktoberfest at noon when he inserted the tap into the first keg.

Munich's Oktoberfest, the world's biggest beer festival, opened Saturday under heightened security following a string of attacks in Germany attributed to jihadists.
